🎨 Palette: 빈 디렉토리 상태의 시각적 명확성 개선

[seonghobae]

💡 What: 빈 디렉토리 상태(.empty-dir)의 CSS 스타일을 개선하여 중앙 정렬, 점선 테두리, 배경색 및 넉넉한 여백을 추가했습니다. 다크 모드에 대한 스타일도 올바른 CSS cascade 순서로 함께 추가되었습니다.
🎯 Why: 빈 디렉토리일 때 단순히 텍스트만 표시되면 오류나 미완성 UI로 오인될 수 있습니다. 이를 명확한 빈 상태(Empty State) 디자인으로 변경하여 사용자 인지성을 높였습니다.
📸 Before/After: 단순 텍스트 표시에서 명확한 박스 형태의 플레이스홀더로 변경되었습니다.
♿ Accessibility: 충분한 대비(contrast)를 가지는 색상을 사용하여 시인성을 확보하였습니다.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in:6 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Closing as superseded by the protected base and draft canonical #360. The current generated empty state already has role="status", decorative-icon semantics, flex alignment, and existing tests. #360 owns the remaining evidence-based contrast, separators, focus/hover treatment, reduced-motion, browser regression, WCAG 2.2 doctoring, and changelog after #363. No stale check or review from this already-landed duplicate is reused.
